TANK-MOLD.

SPECIFICATION forming part of Letters Patent No. 710,596, dated October7, 1902.

Application filed July 9 1902. Serial No. 114,948. (No model.)

To all whom, it may concern:

Be it known that I, ANSELMO P. MORRIS, a citizen of theUnitedStates,residing at Parma, in the county of Jackson and State ofMichigan, have invented a new and useful Tank- Mold, of which thefollowing is a specification.

My invention is an improved mold adapted for use in the construction oftanks and the like of cement or other plastic material; and it consistsin the peculiar construction and combination of devices hereinafterfully set forth and claimed.

The object of my invention is to provide an improved form or support tobe used in the inner shell of the mold and which is adapted to beadjusted to enable it to be used in connection with molds which vary insize and to facilitate its removal from the inner shell.

In the accompanying drawings, Figure 1 is a top plan view of my improvedtank-mold form or support, showing the same disposed in operativeposition in the inner shell of the mold. Fig. 2 is a vertical transversesectional view of the same.

In the embodiment of myinvention I provide a number of standards 1, fourbeing here shown, each of which is preferably made of a flattened bar ofmetal of suitable dimensions having its lower end bent inwardly to forma supporting-foot 2. On the inner side of each standard, near the lowerand upper ends thereof, are brackets 3 4, each of which is preferablybent from a single piece of metal of the kind used in the constructionof the standards. Each bracket has a lower portion a, that bears againstand is riveted or otherwise secured to the inner side of a standard,anoifset portion b,forming a space 0 between the bracket and thestandard,w hich space is open at its upper side, and aninwardly-extending substantially horizontal arm or lug d at the upperend of the offset portion 17, said lug having an opening. The standards1 are disposed in pairs and are diametrically opposite each other. Eachpair of the standards is provided with a pair of connecting brace-rods5. Each of the said brace-rods comprises a main arm 6 of suitable lengthhaving at one end a pair of forked arms, which extend respectivelyupwardly and downwardly and inclined outwardly therefrom. The upper arm7 of each fork has its outer end bent horizontally, as at 8, to form aneye adapted to bear on the lug b of one of the upper brackets 4 and isconuected thereto by a pin 9. The lower arm 10 of each fork has itslower end turned downwardly, vertically, as at 11, to form a connectionwith the lower bracket 3, the downturned portion 11 entering the openingin the lug or arm I) of the lower bracket. The respective arms 6 of thebrace-rods 5 are disposed side by side and are connected together bykeepers 12, which are slidable on the arms 6, whereby the brace-rods maybe extended longitudinally and adjusted as may be required, and the saidkeepers are provided with set-screws 13, by means of which thebrace-rods when adjusted may be firmly clamped and secured.

The standards 1 in the operation of the device are disposed against theinner side of the inner shell 14 of the mold-section, the said innershell and also the outer shell 15 of the mold-section being indicated inthe drawings in dotted lines. I also provide a pair of supporting-rims,each of which is a hoop, preferably made of bar iron or steel bent incircular or other suitable forum-according to the shape of the mold, andhaving its ends overlapped, as at e. Thereby each of the rims is adaptedto be enlarged or contracted in diameter, as may be required to fit itin the inner shell of the mold. The lower rim 16 fits in the recesses cof the lower brackets 3, bears against the inner sides of the standards1, and is secured in place by wedge-keys 17, which are inserted in thespace between the rim and the offset portions 1) of' said lowerbrackets. The upper rim 18 is likewise fitted in the spaces a of theupper brackets 4c. The overlapped portions of each of the rims areconnected together by keepers19, having setscrews 20, by means of whichthe rims may be secured when adjusted. It will be understood that bythis construction of the form or support the same is enabled to bevaried in size, so that it may be used in the molds employed for makingtanks of various sizes, and that my improved form or support may bereadily applied to and removed from a mold.

Having thus described my invention, I claim- 1. A mold-support of theclass described, comprising standards, to bear against the inner shellof a mold, expansible connectingrims supported by the standards andbraces connecting said standards together in pairs, the said bracesincluding longitudinally-adjustable elements, substantially asdescribed.

2. A mold-support of the class described, comprising standards to bearagainst the inner shell of a mold, expansible connectingrims supportedby the standards and detachable therefrom and longitudinally-adjustablebraces connecting said standards together in pairs, substantially asdescribed.

3. A mold-support of the class described comprising standards to bearagainst the inner shell of the mold, expansible connectingrims supportedby the standards and longitudinally-adjustable braces connecting saidstandards together in pairs and detachable therefrom, substantially asdescribed.

4. A mold-support of the class described, comprising standards to bearagainst the inner shell of a mold, connecting-rims, detachably fitted tothe standards, and braces disposed diametrically with reference to therims and detachably connected to the standards, substantially asdescribed.

5. A mold-support of the class described, comprising standards to bearagainst the inner shell of a mold and having brackets on their innersides, said brackets having re cesses formed between their upperportions and the standards, which recesses are open at their uppersides, expansible connecting-rims to lie in said recesses, andlongitudinally-adjustablebraces secured to the brackets and connectingsaid standards together in pairs, substantially as described.

6. A mold-support of the class described comprising standards to bearagainst the inner shell of a mold and having brackets on their innersides, expansible connecting-rims, means to detachably secure the rimsbetween said brackets and standards, and braces, to connect thestandards together in pairs, and

detachably connected to said brackets, sub-
